Lazio disappointed us with their performance against Ludogorets, and I do not expect the game to end without a single goal scored. Despite dominating the game, Lazio failed to score against Ludogorets. Lazio had 20 shots, 6 were on target, but they failed to score a single goal. I had the same views as you because Lazio has been in excellent form this season, I expected them to defeat Ludogorets by more than three goals, I gave them to score more than 2.5 goals. Because they were able to defeat Porto and Twente while remaining at the top of the table. However, Ludogorets earned their first Europa League point with a draw against Lazio.
However, I wasn't able to see the Lazio game against Ludogorets, but I had an opinion that they failed to put their best players in the game since they were already at the top of the league, even if they lost, they would not lose their opportunity to make it to the next round. It seemed confusing that Lazio failed to defeat a club that had lost their first four Europa League games. Lazio is now leading the league with 13 points, despite the draw.
If you pay attention to the game pattern applied by Lazio coach, Marco Baroni in every match there will be some changes. It seems he adjusts his tactics based on the opponent they face. Marco Baroni often rotates some of his players to change positions or with players on his bench. Only a few players will continue to be used as starters. So too with the formation applied, sometimes he uses 4-2-3-1, 4-4-2, or 4-3-3. Apart from the draw obtained when facing Ludogorets, he is a coach who is difficult to predict.
